Pulse Value Register:Configures the number of Wh / VARh required to generate one pulse on the Wh or VARh pulse outputs. ie: if this register is set to 10, ten Wh must accumulate before a pulse is triggered. In this case the pulse value would be 10 Wh / VARh per "click". As with the current and power registers, the proper PT/CT ratio must be applied to the pulse outputs for proper engineering units. Ie: if the meter is designed to output 1 pulse per 10Wh, and the CT ratio is 800:5, the value of one click becomes 10 * 80 0/5 = 1600 Wh (1.6kWh)

Setting the Pulse Value Register to a value of “0” sets the output pulse value to 0.1 Wh/VARh ( x CT/PT ratios) per pulse. Ie: with a CT ratio of 800:5, the pulse is 16 Wh/pulse. At settings of “1” or higher (>=1Wh/pulse), the pulse output is a 100ms contact closure. At a setting of “0” (0.1Wh/pulse) the pulse duration is 50ms with a minimum 50ms interval between pulses. This may have a bearing on PLC/DDC systems, as some are incapable of detecting short pulse durations.
